Infinitive verbs are often identified in the English language by a preceding "to" before the base form (i.e., to go, to work, to edit); this is known as a full infinitive. An infinitive with any words between the "to" and the base form (e.g., "to boldly go") is called a split infinitive. While many people believe that split infinitives are ungrammatical, some authorities disagree.[2]
